An orthogonal experiment was conducted to evaluate effects of Acid Red G mass fraction,melamine-urea-formaldehyde resin（MUF） concentration,Na,2,CO,3, mass fraction and curing temperature on physical and mechanical properties of fast grown Chinese Fir wood modified with the above-mentioned compound and process.Results showed that the MUF concentration had a significant influence on wood density,anti-swelling efficacy（ASE）,modulus of elasticity（MOE）,modulus of rupture（MOR）,compressive strength and color fastness.The dye mass fraction had significant influence only on wood color.The Na,2,CO,3, mass fraction significantly affected wood color fastness only.The curing temperature significantly affected only the ASE.Based on a comprehensive evaluation,the optimal process was as follows:30% of MUF concentration,1% of Acid Red G mass fraction,0.5% of Na,2,CO,3, mass fraction and 100℃ of curing temperature.The modified wood samples had excellent physical and mechanical properties with good decorative performance,which are desirable for making solid wood furniture and other solid wood products.
